Crews have added a continuous northbound HOV lane from the Auburn Super Mall to Interstate 405 in Renton. This new lane, as well as new metered on-ramps, will increase safety and reduce congestion on this important corridor.
Metal guardrails will reduce median crossover collisions. Six modified off-ramps will decrease the chances of rear-end collisions by creating a smoother transition from the highway to the off-ramp. Widening the inside shoulder will provide space for emergency use. New lighting improves visibility.
The new HOV lane and bypass lanes on the on-ramps will reduce congestion.
| Protects Environment
Installation of nine retaining walls will reduce impacts to wetlands and wetland buffers. Stormwater treatment facilities will remove heavy metals and other debris from highway runoff.
